Definitions
- the present invention relates to novel N-phenylsulfonyl-N'-primidinyl- and -triazinylureas which have a herbicidal action and an action regulating plant growth, to processes for producing them, to compositions containing them as active ingredients, and to the use thereof for controlling weeds, particularly selectively in cultivated crops, or for regulating and reducing plant growth.
- N-phenylsulfonyl-N'-pyrimidinyl- and -triazinylureas correspond to the general formula ##STR2## wherein A is 3,3,3-trifluoropropyl or 3,3-difluorobutyl,
- R 1 is hydrogen, halogen, nitro, cyano, C 1 -C 4 -alkyl, C 1 -C 4 -haloalkyl, C 1 -C 4 -alkoxy, C 1 -C 4 -alkylthio, C 1 -C 4 -alkylsulfinyl, C 1 -C 4 -alkylsulfonyl, --CO--R 6 , --NR 7 R 8 , --CO--NR 9 R 10 or --SO 2 --NR 11 R 12 ,
- R 2 is hydrogen, halogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, C 1 -C 4 -alkylthio, C 1 -C 4 -alkylsulfinyl or C 1 -C 4 -alkylsulfonyl,
- R 3 and R 4 independently of one another are each hydrogen, halogen, C 1 -C 4 -alkyl, C 1 -C 4 -haloalkyl, C 2 -C 4 -haloalkoxy, C 1 -C 4 -alkylthio, C 1 -C 4 -haloalkylthio, C 1 -C 4 -alkoxyalkyl, C 1 -C 4 -alkoxy or --NR 12 R 13 ,
- R 5 is hydrogen, C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy
- R 6 is C 1 -C 4 -alkoxy, C 1 -C 4 -haloalkoxy, C 1 -C 4 -alkylthio, C 2 -C 6 -alkoxyalkoxy, hydrogen, C 1 -C 4 -alkyl or C 1 -C 4 -haloalkyl,
- R 7 , R 8 , R 9 , R 10 , R 11 , R 12 and R 13 independently of one another are each hydrogen or C 1 -C 4 -alkyl
- E is nitrogen or the methine bridge
- Z is oxygen or sulfur
- Urea compounds, triazine compounds and pyrimidine compounds having herbicidal activity are known in general.
- Sulfonylurea compounds having a herbicidal action and an action regulating plant growth have recently been described, for example, in the European Patent Publications Nos. 44210, 44807, 44808 and 44809.
- alkyl in the definitions is meant straight-chain or branched-chain alkyl, for example: methyl, ethyl, n-propyl, i-propyl, the four isometric butyl groups, n-amyl, i-amyl, 2-amyl, 3-amyl, n-hexyl or i-hexyl. Methyl and ethyl are preferred.
- alkoxy is meant: methoxy, ethoxy, n-propyloxy, i-propyloxy and the four isomeric butyloxy groups, in particular however methoxy, ethoxy or i-propoxy.
- alkylthio examples include: methylthio, ethylthio, n-propylthio, i-propylthio and n-butylthio, especially methylthio and ethylthio.
- alkylsulfinyl examples include: methylsulfinyl, ethylsulfinyl, n-propylsulfinyl and n-butylsulfinyl, in particular methylsulfinyl and ethylsulfinyl.
